Product Description
The free-machining version of MONEL alloy 400.
A controlled amount of sulfur is added to the
alloy to provide sulfide inclusions that act as chip
breakers during machining. Other characteristics
are essentially the same as those of MONEL alloy
400. Used for meter and valve parts, fasteners
and screw-machine products.
